TREASURIES-US yields fall on report of US-Iran deal

WASHINGTON, May 28 (Reuters) - Yields on benchmark U.S. Treasury notes fell late Thursday morning following a media report that the United States and Iran had made a breakthrough in their efforts to end their three-month-old war.

The news site Axios reported Washington and Tehran had reached an agreement on a memorandum of understanding to extend a ceasefire pending further negotiations but were still awaiting approval from U.S. President Donald Trump.

Earlier, yields had eased off session highs following a batch of mixed economic data showing weaker growth and steady inflation. The less-than-stellar economic numbers could ease pressure on the US central bank to maintain or raise interest rates.

"What the numbers point to today is simply that we have a stagflation problem," said Peter Cardillo, chief market economist at Spartan Capital Securities. "And that's a big problem for the Fed."

Also on Thursday, Iran targeted a U.S. air base in Kuwait following a U.S. strike on what American officials called an Iranian drone operation near the Strait of Hormuz. The renewed violence underscored the fraught nature of negotiations to turn April's tenuous ceasefire into an agreement to end the three-month-old war that has choked global fuel supplies and clouded the outlook for U.S. monetary policy.

The yield on the benchmark U.S. 10-year Treasury note fell 2.2 basis points to 4.459%. The yield on the 30-year bond fell 1.9 basis points to 4.992%.

A closely watched part of the U.S. Treasury yield curve measuring the gap between yields on two- and 10-year Treasury notes, seen as an indicator of economic expectations, was at a positive 43.9 basis points.

The two-year U.S. Treasury yield, which typically moves in step with interest rate expectations for the Fed, fell 1.5 basis points to 4.018%.

The breakeven rate on five-year U.S. Treasury Inflation-Protected Securities (TIPS) was last at 2.556% after closing at 2.551% on May 27.

The 10-year TIPS breakeven rate was last at 2.412%, indicating the market sees inflation averaging about 2.4% a year for the next decade. (Reporting by Douglas Gillison in Washington; additional reporting by Stephen Culp in New York Editing by Nick Zieminski)
